Application ledMarch 1,1882'. `(Nomodel.) Y

To cl'lwhom fit may cmwern: Be it known that I, OMAR Illinois, have invented certain new and useful l 5 Improvements in Lubricators; and I do here-4 by declare' that the following is a full, clear,

' and exact description thereof, reference being p 'r ters Patent of 'the United States No. 242,327,

granted to me May 31, 1881,' were provided with a valve that opened intermittingly by the zo motion of amachinery part. Such an arrangement, however, has the disadvantage, rst,

that the machinery might stop just in the position when the valve is held open, when all oil will run out of the lubricator; and, second,

z5 that such a lubricator will' not feed oil into a chamber filled with steam or compressed air.

Now, it is the object of my invention to produce a lubricator provided with a small vplunger that is reciprocated in a cylinder and op,

`3o crates like a pump to force automatically, by

the motion of the machinery, acertain quani-ity of oil with each stroke through one or several check-valves placed between this pumpl and the part or partsto be lubricated. There 55 fore my invention consists in the peculiar devices and combinations ot' devices employed `by me for this purpose, as fully hereinafter described and specifically claimed.

g In the accompanyingdrawings, Figure l repf 4o lesents a sectional view of l'yim proved lubris, H. JEWLL, of: hicago, 'in the county of Gook and State of' my lubreator attached for feeding oil into the stealth' lieti; by 'the motions of the cross-head.. Lik"ghetters designate corresponding parts 'in all theigures. y A denotes the cup-shaped base of the lubri- 55 cater, having `a screw-threaded stem, a. A vertical oil-hole, b, extends centrally through the base A and screwstem a, and is countersunk on its bottom end to form a seat for a concentrictherewith, the base A has a tubular extension, c, which is bored to form the oilpump cylinder, and this extension is perforated near its lower end by two small holes, d.

'C is the cup-shaped cap 'of the lubricator, 65 and D the gseiture'clampet`riiet\veenthcp aud base. This glass tube rests against packing-rings, and 'thbase and cap are connected outside of the glass tube` by screw-rods E.

F is the plungenrod, which passes through 7o a Binding-box, e, in the top of cap C, down through the center of -the lubricator, and itsl enlarged end f enters the tubular extension c of base A, and is turned to t close therein and so, asto form. the plungerhead. The upper end of the plunger-rod above' the stuingbox is screw-threaded and passes through the inner end ot' a horizontal arm, G, being provided with adjusting or clamping nuts g above and below said arm. At the outer end of the arm G is formed a socket having a set-screw, h.

Another arm, H, is secured vuponv the operating-rod I by vmeans o'f a.set-screw, c', and its inner cylindrical end is inserted into the socket of arm G, and is secured in the desired posi tion by the set-screw h. By this arrangement, as will be noticed, the ength of arm-connec tion G H cansbe varied to accommodate it to the exact distance between the rods F and I.'

conical check-valve. Above thisoil-hole b, and 6o The operating-rod lis guided by means of go I cap G and glass tube D, and prevents 4the roo splashing of the oil into the cap, as would be the case. when the lubricator is attached to the stub end of a connecting-rod, and a perforated diaphragm, lil, is clamped in the lower joint of the lubricator, and is to act as a strainer for the oil before such oil can enter the perforations d in tube c, so as to prevent these holes from being clogged by solid matter that might be contained in the oil.

The cap C has a screw-plug, in., which is removed when itis desired to lill the lubricator with oil. Through this screw-plug may be formed a small ventopening for admitting air, so that the oil can' ilow from the lubricator, and by reason oi' its connection with one side of the chamber above diaphragm Lthe oil will not he splashed through the same. The opening in the diaphragm L around the plunger rod Fhas to be large enough so that the oil, when poured in the filling-opening, will run down into the body ofthe luhricator.

rIhe stem c of base A. ofthe lubricator is screwed into a thimble, N, which forms the chamber for accnical check-valve, iz, which is pushed against its seat in the bottom of stem a by a spiral spring, o. rlhis thimble N has a screw-neck to its bottom end, which enters a The end of this valve-casing; 0 is screw-threaded, and, as shown in Fig. l, is coupled with a. block, P, that-is bored to form a guide i'or the lowerend ofthe operatin g-rcd I, and is screwed into the head Q ot' aj cylinder, R. The block I is provided with a smiling-box, s, and the' operating-rod projects 'into the cylinder sutliciently to be pushed upward by the piston S when arriving at the end of its stroke. In this case an annular channel is formed around the operating-rod I, below the stui'iing-hox s, that' communicates with the port in valve-casing 0 and with the interior oi the cylinder. This dethe air-brakes; but itinay as well be used for upright steam or gas en lcines.

The piston Swith each stroke will push the operatingrod I upward, wherebythc plunger fis raised in the cylindrical extension c, and a partial vacuum is created in the space between plunger j' and the 'check-valve n, which will drawa certain amount'ot oil into saidspace through vperforations d. As soon as the operating-rod I is released again the spiral spring;` J will rpush it downward, and also the plunger f, which in its downward motion will close the perforations d and will` force the oil through the check-valves it and 1i into the cylinder.

In Figs. 4 and 5 the lubricator is secured into the upper portion of the strap t' of a connecting-rod, T, the opening that receives it being extended through to the crank-pin U. Iothe head of this cranlr'pin` may either he secured a beveled lifting-plate, n, as shown in Figj, or said head may be notched, as shown in Fig. 7

The end of the operating-rodlbcing adjusted either to be lifted by the beveled plate u or to ridc upon the periphery ofthe crank-pin head', such rod I will he reciprocatcd with each revolution of the crank, when the plunger willforce a small quantity of oil to the crank-pin.

In Fig. 8, Wrepresents a locomotive-cylinder; w, the steam-chest ou top of it; X, the guides, and Y the cross-head.

My lubricator is secured upon one end ot' the steam-chest cover, with the oil-inlet into the center ot the same througha gooseneclr, y.

A bell-crank, Z, is pivoted over the guides to the cylinder-head, and is connected to a lever, z, that is pivoted to the steam-chest cover arriving at the end of its Lstroke, will strike 'against one arm ofthe bell-crank Z, whereby the rear end oi' leverlz will be lifted. which again will raise the operating-rod I and the plungerf, connected therewith, audthus, while thelocoinotiveisrunning,theuecessaryamount of oil will be forced from the lubricator into the steam-chest.

The greatadvantage gained by the above arrangement is that whenever the machine stops, no matter in what position, no oil will ilow from the lubricator, and that when the machine is running the supply of oil will be fed automatically in proportion to its speed.

This lubricator being thus reliable and economical, its construction is simple and its arrangements such that it. cannot get out'of order, whileany one ot its parts is easily accessible for repair when it becomes necessary.

I have shown `and described a. few of many devices for attaching this lubricator to and operating by parts ot' the machinery; and I do not wish to be restricted to the particular arrangements shown, since they are manifold,

land muy be different for every class or style of machinery. v
